About this Add-on

The extension is intended for checking grammar using LanguageTool (http://www.languagetool.org/) facilities (in particular, the extension uses its webserver). Though it can work without any further customization, it is strongly recommended to setup local LT server (see http://nuald.blogspot.com/2009/10/thunderbird-grammar-checker-extension.html), and change the extension settings to correspond with your server. By default, the extension uses the small-scale server, which can't handle enormous load (and of course, it is not so suitable from privacy point of view).
